Automate Your Browser(s)
the Easy Way
Build scrapers, automations, AI agents and MCP servers. In your browser or across millions of them, all with a simple API.
// Get your connected browser and create a page
const [ browser ] = await client.listDevices();
const page = await browser.newPage();
// Extract data from a website
await page.goto('https://example.com');
const data = await page.extract({
title: 'h1',
description: 'p'
});Core Features

Persistent Sessions
Uses existing browser sessions, cookies, and authentication. No need to log in each time your automation runs.
Low Resource Usage
Minimal resource utilization compared to Puppeteer, Selenium, and other tools that spawn separate browser instances.

Powerful tools for complex automation needs
Powerful Data Extraction
Extract structured data from any website with our intuitive JSON-based selector system. Target elements precisely, handle nested data, and get exactly what you need.
- Extract simple text, attributes, or properties
- Build complex data models from web content
- Target elements with precise CSS selectors
// Extract structured data with intuitive selectors
const products = await page.extract({
items: {
_$r: '.product', // Find all products
name: '.product-name', // Extract name
price: {
_$: '.price', // Extract price text
pipes: ['parseNumber'] // Convert to number
},
rating: '.rating-stars',
inStock: '.stock'
}
});Smart Data Transformations
Clean, format, and convert extracted data with powerful transformation pipes. Handle currency, dates, numbers, and text processing automatically.
- Convert price strings to actual numbers
- Parse dates and times in various formats
- Clean text data with trimming and case conversion
// Handle various data formats automatically
const cleanData = await page.extract({
price: {
_$: '.price', // "$1,299.99"
pipes: ['parseNumber'] // → 1299.99
},
publishedOn: {
_$: '.date', // "Posted on Jan 15, 2024"
pipes: ['parseDate'] // → "2024-01-15T00:00:00Z"
},
title: {
_$: 'h1', // " PRODUCT TITLE "
pipes: ['trim', 'toTitleCase'] // → "Product Title"
}
});Extract Structured Lists
Extract complete datasets from web pages - whether it's search results, product listings, or any repeating elements - with our powerful list extraction system.
- Extract entire product catalogs in one call
- Handle nested lists and hierarchical data
- Build complete datasets ready for analysis
// Extract an entire search results page
const searchResults = await page.extract({
results: {
_$r: '.result-item', // Find all results
title: 'h3 a', // Get title
url: {
_$: 'h3 a', // Get same element
attribute: 'href' // Extract link URL
},
rating: '.stars', // Get rating
price: {
_$: '.price', // Find price
pipes: ['parseNumber'] // Convert to number
}
}
});Powerful Page Interactions
Interact with pages just like a human would. Click buttons, fill forms, handle complex navigation patterns, and dynamic content loading.
- Fill forms and submit data easily
- Handle pagination and infinite scrolling
- Wait for dynamic content to load
// Interact with forms and dynamic content
const page = await device.newPage();
await page.goto('https://example.com/login');
// Fill login form
await page.type('#username', 'myusername');
await page.type('#password', 'mypassword');
// Click login button and wait for navigation
await page.click('.login-button', {
waitForNavigation: 'networkidle2'
});
// Wait for dashboard to load
await page.waitForSelector('.dashboard-content');Build AI Web Tools with MCP
Connect AI models to your web apps using the Model Context Protocol. Let AI access web interfaces without exposing your credentials or sensitive data.
- Create secure AI agents for internal apps
- Keep credentials secure with sandboxed access
- Build custom MCP servers for AI integration
// Create an MCP server for AI integration
const mcpServer = await client.createMCPServer({
allowedOrigins: ['https://chat.example.ai'],
allowedSelectors: ['.content', 'nav', '.results'],
rules: [
{
url: 'https://app.example.com/**',
capabilities: ['read', 'click', 'extract']
}
]
});
// Start server and get connection URL for LLM
const serverUrl = await mcpServer.start();
console.log(`MCP Server URL: ${serverUrl}`);Simple, Transparent Pricing
